This adds support for much larger numbers of disks in VMs. In my case, I wanted this so I could verify a config before deploying to a multi-array server.
The core limitation is that qemu virtio-blk-pci disks occupy a PCI slot each, and a large array can quickly exhaust available slots. This uses a PCI-to-PCI bridge to add another 32 slots, and, if we have more than 31 disks, starts daisy-chaining more bridges onto that.
